More than a half-pound of cocaine and a loaded handgun were seized Jan. 28 when police busted two men in the parking lot of the Melville Marriott, the Suffolk County District Attorney’s office has confirmed.

A spokesman for District Attorney Thomas Spota said John Martin, 53, of North Babylon, and Joseph Rosati, 45, of East Islip, “acted in concert to possess more than 8 ounces of cocaine.”

Martin was charged with attempted criminal possession of a controlled substance, an A felony, and first-degree conspiracy, a B felony.

Rosati faces the same charges plus a felony weapon possession charge for allegedly having a loaded .380 Smith & Wesson during the commission of a felony, the DA’s office said.

According to online court records, the men were arrested at 12:21 p.m. A Suffolk County police spokesperson wouldn’t comment on the case, calling it a confidential investigation.

Martin was freed on $450,000 bond Jan. 30, according to online court records. He was due back in court after press time Feb. 3. So too was Rosati, who was held on $1.5 million bond and $500,000 bail, according to the district attorney’s office.
